What qualities does the color blue have that best illustrate feeling blue? Questions like this were the inspiration behind German animation artist Sebastian Buerkner's new solo show at London's Showroom gallery. His aim is to represent different emotions through movement, and to this end he uses speed, weight, color, form, and clarity of line to illustrate the feeling of, well, feelings. Using flash, Buerkner hopes to unlock each viewer's subconscious and in the process carry out a high-tech form of hypnosis. So, the next time you feel an irrational mood swing, you can blame it on the emotional trigger of a particular hue, which sounds much saner than putting it down to an irritating colleague or bad lunch experience. Or at least more scientific.
